View 2 Replies View RelatedAndroid :: How To Obtain The Current Bitmap Of A Canvas
Nov 16, 2010I want to get the current bitmap associated with my canvas so I can perform operations on it. I can't see how to do this though.
I've seen some examples where you create a bitmap and set the canvas to use this bitmap, so obviously you can then access it later, but I'm using the canvas returned from a SurfaceHolder so there's no constructor.
For instance, examples often show this kind of thing:
CODE:...........
So at this point I can see bmp.
In my case, the canvas is obtained by:
CODE:......
So how can I get the bitmap for c?
In short, my aim is to capture the current canvas contents where I have drawn "stuff", and make a copy of it, reversed, to put underneath. Like a reflection. The example of this that I found performed it all via bitmaps, so I assumed I needed to somehow capture the current canvas to a bitmap to then use it.
Android :: Invert A Bitmap When Using Canvas.DrawBitmap?
May 14, 2010I am starting to develop a game. Right now I got a sprite animation going when a player moves across using sprite sheet. In my sprite sheet the character is always facing the same way, left. Now if I want the character to move right, I want it to be facing right. So is there a quick way in android to invert the bitmap after it has been loaded in? Or do I have to create sprite sheet for character facing right?

Sep 10, 2013At canvas there are many methods (canvas.rotate (35); canvas.drawBitmap (myBitmap, x, y, null); and many other things), but the method of mirror reflexion of image is absent (or I have not found it).

Mar 25, 2010I want to draw a bitmap on a canvas with bigger size than it is. I can use canvas.drawBitmap(bitmap, null, destRect, null); but that gives a poor quality, as the result is pixelated, if the source image is sightly smaller than the destination rectangle. How can i draw my bitmap using bilinear or bicubic resampling?

Android :: Storing Bitmap Images For Game Animation

Android :: Rotate Bitmap With Canvas.rotate
Sep 24, 2010As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!

It showed up on the 2nd or 3rd day after getting the phone. It looks like a yellow sheet of paper with a dog-ear in the bottom-left corner. I had installed a couple of notepad apps and uninstalled all except for one called Note Me. I've checked Task Manager and it doesn't appear to be running. Deleted all notes in Note Me, checked its options, and the author's web page doesn't show this icon.Pocket your world - Home of software solutions for your iphone, gPhone and Blackberry Anyone recognize this icon?

Feb 8, 2011I have ordered a Zenithink ZT-180-102A and plan to use it to view sheet music for the band I play in, and turn the pages with a USB foot switch that sends a PgDn key to Acrobat Reader.
I would think that the tablet will be (just) big enough to view A4 PDF sheet music at 10.1" (would have preferred slightly bigger).I'm hoping Adobe Acrobat Reader for Android can go full screen and respond to PgDn messages.Battery life seems a bit light, but figure I can run it from the power adapter if required.how well the screen would work in sunlight.If I'm reading the foot switch description right, I can configure the key press via the software on a Windows machine, then plug it directly into the Zenithink as a standard HID device.

View 3 Replies View RelatedAndroid :: J2ME Like Sprite
Sep 25, 2009For my useless project of the month I'm working on a 'emulator' to run J2ME programs on Android. But now I'm stuck with the J2ME Sprite implementation. Specifically the transformations used in it.
In my Sprite I have a bitmap with three character images. I would like to paint the second frame mirrored or rotated 90 degrees. What would be the best way for it?
I have following code that paints the given frame without any transformations.
frameX, frameY are frame position coordinates on give sprite bitmap.
Rect src = new Rect(frameX, frameY, frameX + spriteWidth, frameY + spriteHeight);
Rect dst = new Rect(paintX, paintY, paintX + spriteWidth, paintY + spriteHeight);
canvas.drawBitmap(image, src, dst, null);
As I understand I need to make some matrix magic on the canvas, but I have not been able to figure this out.
Android : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It
Apr 2, 2009I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

Android : How To Color Key 2d Sprite Backgound
Mar 19, 2009I am working on a 2d library for creating a game including sprite collisions, sorting and animation converting (.spr to Java classes/ bmp's).
At first I used png's with the background color being transparant (24 bits png image) but I want to use 256 color bitmaps with the background color being transparant.
Is this possible to do color keying in android? I looked at several other threads about this topic but the all ended without a solution.
Also I am now using the canvas.drawBitmap to render my sprites, but will using opengl be faster?
HTC Incredible :: Micro USB Side Of Cable In Sprite

Luckily I still have the charger for my old BlackBerry Storm.

Mar 13, 2010After following Matlock's post about upgrading to 2.1 I tried to restore all of my files using Sprite Mechanic. (Going back and re-reading his post he says that it doesn't work in 2.1-DOH). After installing Astro I tried re-installing Sprite Mechanic from the backup folder that I made with Sprite Mechanic thinking that was the way to get all of the back-up apps out of the back-up folder and onto the phone. I started Sprite Mechanic and proceeded to push the "Restore" tab and it brought up a list of all backed-up apps. I scrolled through them, deciding which ones I really wanted back and which ones I could do without, and then pushed the "Restore" button. Well, my phone froze up and would only display the status bar across the top. I tried pushing different buttons, but to no avail....
